yellowing and wilting lower fan leaves 4thweek flowering

[maddox420]

Help I just started 4 week of flowering and the lower fan leaves are yellowing and dieing I'm useing fox farm nutes and ocean forest and liquid kool bloom my Ph is 6.5 temps around. 77 47% humidity. The rest of plant looks healthy any ideas

Two things, I see a P- (phosphorous deficiency) as evidenced by the reddened/purpled petioles. Second I see is the plant using up nitrogen. It's a bit early for this kind of fading, I suggest pushing a little bit more N and P. I also suggest raising the humidity to around 50%-55%.

 

[maddox420]

That's what I thought at first but I should be useing plenty maybe a lockout I always get plenty of runoff

 

[Seamaiden]

Are you keeping the pH locked at 6.5? If so, I suggest letting it drift both up and down. The whole plant photos are very difficult for me to make out, they appear to be blown out (f-stop, white balance, aperture, I'm terrible with the photog stuff).

 

[maddox420]

No it varies. From 6.5 to 6 what would you recommended doing I think I'm gonna flush tonight

 

[maddox420]

I just got home and more of the fan leaves are turning yellow and are limp I flushed then added a does of n and some grow big can anyone help

There lower fan leaves, just pick them off, and keep it moveing. I wouldn't even worry about it. They die after they get so old. Plants don't keep all of there leaves for ever. At least that's my experience. But Thats just me.

Also I have noticed that leaves that don't get light, like the bottoms turn yellow not from a N dif., but from lack light.

So I might chalk it up to that. There to shaded. But again. That's just my experience.

If it was just the Leaves I wouldn't be to worried and also the purple red stems really has me thinking something more serious is going on

I guess,.... I really wouldn't worry about purple stems. Like we're did you here that was a bad thing?

Just let the plants grow, they will be fine, your over thinking the hole thing. Clean that basement up, it looks filthy. :)

I've heard some strains do that or it could have something to do with phosphorus

Either A LOT of plants do it, or Im a really shity farmer. Really bro, I wouldn't worry about it. Pick them off, and keep it moveing bro. For me personally I try and get fades in flower. I want to see yellow, red, purple, black, orange, any thing other than a pure green plant. IMVHO after harvest something that's pure green, lacks in the taste department. Plus it smells green. Like wet grass. But that's just me.

IME, the plants that naturally have purpled petioles have stripes on the main stalks, too. However, one of the diagnostics for P- in many vascular plants, not just cannabis, is reddened or purpled petioles, and cannabis often also displays a very dark green color to the leaves as it progresses, and as it progresses further it can then become necrotic spots on the leaves, IIRC mid-plant.

Bo0m, I like to see fading late in flower, but this cat's only 4 weeks in, I think it's too early. Your point about the light may be spot on here, but it's not something I've really experienced.

I'm going to attach my favorite graphics for the benefit of the OP and whomever else may be reading.

I love those fucking charts sea. :)

It's def light, look at his plants, there super leafy, and the tops are a buitiful green no signs of anything. The purple stems, lol he's just being a worry wart. Lol his plants are fine, he's just all newb worried.

If he gets all worried about this, he's gonna fuck shit up just based, on him doing shit that doesn't need to be done. Like fucking flushing at weed 4.

I fucking hate George Cervantes. The dudes book is the worst fucking guide to growing pot. He's a doush bag.

Yea I guess im worrying to much they do look nice other than the lower fan leaves this is my first indoor grow so it will take me a few to get a little experience under my belt. I've been following the fox farms feeding schedule it does have a flush at week 4 I'm just gonna keep doing what I have been doing and continue reading and taking as much in as I can here's a new pic

I've met the man, his name is Jorge, and he's a very nice person, very genuine and great to talk to. I've actually ended up becoming friends with one of his traveling companions.
If you think his book(s) is/are crap, why don't you write your own? You can call it Bo0m! Like That! :D

I still think his plant shouldn't be yellowing like that at week 4, and I would still give them a small push of nitrogen. I still think the reddened/purpled petioles are an indicator of P not being utilized. Flushing wouldn't help either scenario, would it? I honestly can't tell much of anything about the rest of the plants, even in the second photo, the light's blown out and I can't make out a thing. What I can see looks good, but I can't tell how far up the yellowing goes.

A lot of people think the reddened/purpled petioles are normal. To them I say try this--grow that gal inside with her purple petioles, then try growing her outside in good soil and see what happens. IME, every time, and I mean every time I do that, the girls grown outside lose those purpled petioles. The only exceptions are strains that also have the purple striping on the mains. I'm still trying to work getting rid of that sign indoors. Got it down pretty well outside, inside not so much.
